ESL socket outbound: fail to stop tone detect
by Stephen Wilde 28 Feb '11

28 Feb '11

In an originated outbound session that is in progressing phase, I do, via esl socket outbound, a "tone_detect". When I receive the event "DETECTED_TONE" I do the "stop_tone_detect" but sometimes the stop has no effect and I see in the log the warning: "switch_core_session.c:1955 Cannot execute app 'stop_tone_detect' media required on an outbound channel that does not have media established" But the media is present (the tone is correctly detected!). The event I receive on this channel are (in sequence) CHANNEL_UUID CHANNEL_OUTGOING CHANNEL_ORIGINATE CHANNEL_STATE - CS_INIT CHANNEL_STATE - CS_ROUTING CHANNEL_STATE - CS_CONSUME_MEDIA CHANNEL_PROGRESS CHANNEL_PROGRESS_MEDIA CHANNEL_STATE - CS_EXECUTE CHANNEL_EXECUTE CHANNEL_PARK then I do the "tone_detect" and I receive: CHANNEL_EXECUTE MEDIA_BUG_START CHANNEL_EXECUTE_COMPLETE DETECTED_TONE so I do the "stop_tone_detect" that fails in the log Please, can anyone address me to solve this issue?

FreeSwithc not handling no SDP INVITE properly for video call
by George Lee 28 Feb '11

28 Feb '11

Hi all, I am having trouble with FreeSwitch handling late codec negotiation for video calls. The call logs are here: http://pastebin.freeswitch.org/15481 I have this line: <param name="enable-3pcc" value="proxy"/> added to the external sip_profile for handling late codec negotiation. I also have <X-PRE-PROCESS cmd="set" data="global_codec_prefs=PCMU,PCMA,H263"/> <X-PRE-PROCESS cmd="set" data="outbound_codec_prefs=PCMU,PCMA,H263"/> in vars.xml for codec support list. The initial INVITE contains no SDP for the caller and once the callee answers the call, it sends the 200 OK with audio (pcma, pcmu) and video (H263) codec capabilities. FreeSwitch forwards the 200 OK to the caller without video codec capabilities. As a result, the video call does not establish properly. Could someone give me a pointer? Thanks, George

freetdm with a400p segfaults
by Jesse Cloutier 28 Feb '11

Im having trouble with getting freetdm to work with a openvox a400p with 4 fxo modules using the latest freeswitch from GIT dahdi installs fine and 'dahdi_hardware' lists it as a TDM400P When I configure freetdm.conf only I can start freeswitch and do a ftdm dump and it displays my span with 4 channels When I configure freetdm.conf.xml freeswitch segfaults on startup I don't know if I need them but ftmod_analog.so and ftmod_zt.so have been built this is my freetdm.conf: [general] [span zt myFX0] fxo-channel => 1 fxo-channel => 2 fxo-channel => 3 fxo-channel => 4 This is my freetdm.conf.xml: <configuration name="freetdm.conf" description="FreeTDM Configuration"> <settings> <param name="debug" value="6"/>     </settings>  <analog_spans>  <span name="myFXO">  <param name="dialplan" value="XML"/> <param name="context" value="Incoming-FXO"/> <param name="tonegroup" value="us"/> <param name="enable_callerid" value="true"/> <param name="enable-analog-option" value="call-swap"/>  </span> </analog_spans> </configuration> Any idea what I am doing wrong? -- Jesse Cloutier Network Administrator Cronomagic Canada 5143411579 x210 jesse(a)cronomagic.com

mod_event_socket message pizza received from BSD machines
by Mauritz Løvgren 28 Feb '11

28 Feb '11

Hi, We are experiencing weird behaviour when using socket connection to mod_event_socket while running FS on FreeBSD and Mac OSX. We send a lot of bgapi and api commands to the FreeSwitch while controlling and monitoring hundreds of sessions. We have created a simple load-test that displays the problem we face. The load-test simply fires the following command continuosly to freeswitch: “bgapi sofia status”, generally as fast as freeswitch can receive it. The following occurs, but only on FreeBSD or MacOSX (10.6.6) (both 64-bit) while using latest version of FreeSwitch: - Replies and events are inter-mixed on the receive stream (the output from freeswitch), causing protocol errors in the receiving client. This does _not_ happen on CentOS or Windows, so we wonder what could be causing this. Is there a problem with threading or socket libs here? We assume that FreeSwitch protect a mod_event_socket inbound connection output stream by locking (or other means) to make sure not any two messages are written ‘simultaneously’ causing garbage in the receiving end?

Dockstar -- FreeSwitch crashing with latest git
by Tom C 28 Feb '11

28 Feb '11

I just did a "make current" on my dockstar (Debian Lenny) for the first time in over a month, and now FreeSwitch crashes at startup. It gets all the way through the boot process, past the final banner, and then I get a segmentation fault. Output below. 2011-02-27 20:51:54.723908 [CONSOLE] switch_core.c:1768 FreeSWITCH Version 1.0.head (git-fd7bbc0 2011-02-26 11-45-19 +0100) Started.

Re: [Freeswitch-users] Fax processing not successful - result (41)TIFF/F file cannot be opened.
by envelopes envelopes 27 Feb '11

27 Feb '11

yes! that is it. the tif file that I used was copied from a sample file included in windows 7 installation. C:\Users\xyz\Documents\Fax\Inbox\WelcomeFax.tif per your tip, I generated the tif file by myself and it worked now. 1) grab a pdf file. 2) sudo apt-get install imagemagick 3) convert -density 204x98 -resize 1728x1186\! -monochrome -compress Fax ./test.pdf ./test.tiff 4) originate loopback/9979 &txfax(/tmp/test.tiff) whoever has FS wiki edit permission please update mod_spandsp. don't let future users frustrated by this damn stupid issue. I also believe this is a bug in mod_spandsp since it can't handle standard windows tif file. Johannes, thanks a lot for your great tip.

Applying multiple limits for calls by sip_auth_username or by sip_received_ip
by Simon J Mudd 27 Feb '11

27 Feb '11

Hi, I was pointed to the limit application as a way to control call usage. This seems quite good for me if I'm paranoid about my FreeSWITCH setup being attacked. http://wiki.freeswitch.org/wiki/Mod_limit gives a cuople of examples using slightly different syntax, one using data="db ..." and the other data="hash ...". However the parameters are not clearly explained. The Rate Limiting calls / Anti SPIT example is what interests me but it's not clear: (1) exactly how the first 2 fields are used, and (2) if I want to set different rates for the same 2 fields but for different time periods if I can or one configuration will affect another one. I had a very quick look at the code but it seems to have changed from v1.0.6 to the current head and I wasn't sure where to look in the "core" code to figure out the usage. Basically what I'm looking to do is very similar to the Rate Limiting example, something like: in dialplan/default.xml: ...  <extension name="limit_exceeded"> <condition field="destination_number" expression="^limit_exceeded$"> <action application="playback" data="$${CUSTOM_SOUNDS_DIR}/limit_exceeded.wav"/> <action application="hangup"/> </condition> </extension> <extension name="limit" continue="true"> <condition>   <action application="limit" data="hash $${domain} A${sip_received_ip} $${MAX_CALLS_FROM_IP_PER_SEC}/1" /> <action application="limit" data="hash $${domain} B${sip_received_ip} $${MAX_CALLS_FROM_IP_PER_MIN}/60" /> <action application="limit" data="hash $${domain} C${sip_received_ip} $${MAX_CALLS_FROM_IP_PER_HOUR}/3600" /> <action application="limit" data="hash $${domain} A${sip_auth_username} $${MAX_CALLS_BY_AUTH_USER_PER_SEC}/1" /> <action application="limit" data="hash $${domain} B${sip_auth_username} $${MAX_CALLS_BY_AUTH_USER_PER_MIN}/60" /> <action application="limit" data="hash $${domain} C${sip_auth_username} $${MAX_CALLS_BY_AUTH_USER_PER_HOUR}/3600" /> </condition> </extension> ... Am I right in assuming that it's necessary to add a prefix when using multiple limits for different periods at the same time? Also I'd like to apply something similar for registration attempts (successful or otherwise), basically similar to the ${sip_received_ip} lines, but am not sure where that would be applied. Could someone point me to the right location? Thanks, Simon

implementing stereo (e.g. portaudio to test it easily)
by MatzeMuc86 27 Feb '11

27 Feb '11

hello FreeSWITCH community, actually it is my first time to use lists like this. I hope I do everything fine. For my project I try to get stereo (and some special features later) integrated in freeSWITCH, especially SIP. TO start with this idea I need to know where I have to activate or implement stereo. In the second I try to play a bit with the portaudio module as I do not have to focus on SDP problems transporting SIP and the need of a SIP client which is able to receive stereo. So I set up some custom moh local media stuff which works finde - using mono. Changing the channels to 2 makes the console telling me that the sound file will be mixed to mono and the sound is quite strange. I would be happy about getting some useful information which modules or configs are the important ones for my idea. Unfurtun ately I have only found some recording stuff about stereo which is not what I want to do. Thank you very much. MatzeMuc86
